Fix clippy::needless_continue lint in code generated by FromDeriveInput

[sbernauer]

In the FromDeriveInput derive macro, in

darling/core/src/codegen/attrs_field.rs

Lines 90 to 93 in 7f7dee7

	quote! {
	#(#names)|* => #push_command,
	_ => continue,
	}

a match statement similar to this is produced:

match foo {
    "bar" => do_something(),
    _ => continue,
}

After enabling the needless_continue lint (as part of pedantic lints) in our codebase, it complained about the match statement generated by darling. It suggests to "drop the continue expression".

I was able to quickly fix the lint, however I'm not sure if the continue is intentional preferred over {}. In which case I'm also happy to change this PR to add a #[expect(clippy::needless_continue)] to the generated code, just let me know!
